1996 - 1997 Centre for Environment, Fisheries & Aquaculture Science (Cefas) Joint Nutrient Study (Jonus) II Plankton Survey

The Jonus II programme was run to examine impacts of nutrients on the coastal pelagic community and consisted of a series of 7 individual cruises using RV Cirolana and the charter vessel Lough Voyager. The survey was conducted in the southern North Sea, the Thames Estuary, The Wash, the Irish and Celtic Sea, the South-Western Approaches and the western English Channel. As part of the survey aims phytoplankton and zooplankton samples were collected. This data consists of the numbers of microzooplankton, along with associated positional data and volumes filtered.
